What happens if your mind lives for ever on the internet?

Imagine that a person's brain could be scanned in great detail and recreated in a computer simulation. The person's mind and memories, emotions and personality would be duplicated. In effect, a new and equally valid version of that person would now exist, in a potentially immortal, digital form. This futuristic possibility is called mind uploading. The science of the brain and of consciousness increasingly suggests that mind uploading is possible – there are no laws of physics to prevent it.
